Guide my choice on diesel: xantia or XM

John Plum · Post by **John Plum** » 18 Mar 2014, 14:44

I'd appreciate guidance in choosing new car.
Currently run Xantia 1.9td estate.
I like the loading space. It's economical on motorway - over 50mpg at 80 mph when unloaded.
Not great around hills and town. Not as good as my BX 1.7td manual for towing.

Attracted by hdi 110 xantia estate, though not driven one. Will go for manual probably due to better towing.
However also seen 2.1 TD estates going with 110 bhp. What are these limps like for performance and longevity?
Also, I could go for an XM hatch, as I think they load as much or more than a BX which was fine.

Guidance appreciated.
John

If you're looking for lower running costs, then run the 1.9 on veg. New veg is under £1ppl, pre-filtered waste veg can be around 60ppl, filter yourself for whatever the raw materials cost (typically 20ppl). Blend with 20% misfuel for further reduction in cost.

If you need more power and torque, then it's easy to get that from the 1.9. A simple and safe tune will easily yield 110bhp, 130bhp is possible on the standard turbo if you want to crank it some more. The turbo will spool much sooner too. All achievable with a couple of simple sockets.

Or use a combination of the above for more power and lower running costs

I like the sound of those mods Evilally. Maybe you have some links?
I didn't find running on SVO so pleasant or economical - seemed to run rough on 100% and I did that for three years.
Q. What is misfuel?
Q. Can an hdi be run on SVO?

I'd really like to hear on views on the 2.1 td vs. 2.0 HDi compared.

I've had a couple of 2.1 Manual XM hatches, and a 2.0HDi 110 Xantia Saloon, a few 1.9 TD Xantia saloons and a 1.9 TD Estate.

The 110HDi wins every time for me. It's quieter, smoother and more economical than the 2.1TD (which is a nice engine, but not that nice). I believe the 2.1 Xantias had the EPIC pump which doesn't like veg and can be finnicky.

There's so many 110HDis and 90HDis about that engine spares are plentiful and cheap in breakers yards. I'd go as far as saying the 110HDi Estate is probably the best, most useful Xantia ever made, unless you are insane and/or rich, then the V6 beats it, but does half the mpg, if you are lucky.

Hey Mike your advice is spot on. Cheers.
I've just win a bid on the following 110 HDI LX estate
http://bit.ly/1mg2abw" onclick="window.open(this.href);return false; with about 171 000 on the clock,
On eBay. Bodywork sounds good. Probably got a front height corrector plastic link fault. Not so cheap at £720, perhaps, but estates seem to be attractive right now.

The other thing is that, properly maintained, the 8v 2.0l HDi engine is virtually bombproof. Yes, things that help them run properly can fail (the EGR comes to mind, whatever THAT is), but (from what I have read) the forum members rate it as one of the best diesel engines made so far.

The height issue is probably down to a sticking height corrector, while the ABS issue could either be a failing sensor or loose reluctor ring. There is also info on fixing that heater issue.

That looks like a good one, needs a couple of things sorting but 171,000 isn't a huge amount for these. There's quite a few on the forum with well over 200k on them, and my brother's mate has my old one (which I bought, ran for 9 months, sold to CitroJim who fixed all it's faults and ran it for about 9 months, then I bought it back off him, then sold it to my brother's mate) and that has 240k on it now and is pretty much spot on apart from wear and tear.

Sounds like a Lexia session would help trace the ABS problem, and that the height correctors need a damn good cleaning and greasing. If you have no Lexia, I guess being in London and Wales, you travel down the M4 sometimes, so feel free to PM me and pop into Twyford for a Lexia session one day.

Q. Can an hdi be run on SVO?

A. NO! Severe wallet damage will be the result

The 110 HDI engine is very good indeed. I've put 118,000 miles on mine since I bought the car. Regular oil and filter changes work wonders for engine longevity.

Egr on hdi 110s and 90s in the 8v engines is not ecu monitored or controlled directly. Its vaccuumm controlled so can be removed.. they are amazing for an electronic engine pleanty reaching 300k plus easilly. My own on 275k..

DO NOT USE ANY SVO OR WVO VEG WHAT SO EVER IN ANY HDI ENGINE. YOU ARE ASKING FOR TROUBLE.

just wanted to point that out. They are strickly a diesel engine only. Power. Just add a tuning box and gain 20bhp. I never found xud td engines particually good on fuel in the xantia.. And in reality an xud struggles 43 mpg in the heavy xantia. Where as the hdi averages 50mpg with a boot full of all my gear!!

As for xm thats a tough point. They need care. But theres also little choice now . The xm is disappearing now. So limited choices. Most later cars from 1997 has lucas epicm rust is becomming a big problem too. Xantia bodys stronger. (Hatch's)

Its not a bloody sticky height corrector!! Arrgghhh. Its the control levers to control the height corrector!!

The levers need freeing up. There nothing wrong with height correctors. They rarely fail unless full of s**t!

also egrs dont play up on these. Its normally the electro valves and vaccum pipes for the turbo wastegate that play up.

Thanks for all your advice and encouragement guys. I understand about the SVO now, just been reading around.

Paul you're right I think , it's the levers, technically. Guess that's what others mean. Better corrected (-:

The height correctors were full of s**t on one of mine and Chris570s was leaking badly. I was up at Jim's while it was being replaced.

I found the HDi no more expensive to run on pump diesel than a TD on veg due to the econonut difference

@Paul What is the tuning box - do you mean air filter?
